GENERAL CHARACTERISTICS
PRODUCT OVERVIEW
The MEV3 series is a new range of high
performance 3W DC/DC converters, offering 3W
of available output power in a previously rated
2W package capable of operation over the full
industrial temperature range of -40ºC to 85ºC.
Available in an industry standard SIP package,
with a pin compatible power upgrade path from
the 1W NMV/MEV and 2W NMK series’, they
are ideally suited for providing local supplies on
control system boards with the added benefit of
3kVDC galvanic isolation.
